The Com­pact Par­ti­cle Ac­cel­er­a­tor Cor­po­ra­tion has de­vel­oped an ar­chi­tec­ture to pro­duce pulsed pro­ton bunch­es that will be suit­able for pro­ton treat­ment of can­cers. Sub­sys­tems in­clude a RFQ in­jec­tion sys­tem with a pulsed kick­er to se­lect the de­sired pro­ton bunch­es and a lin­ear ac­cel­er­a­tor in­cor­po­rat­ing a High Gra­di­ent In­su­la­tor with stacked Blum­leins to pro­duce the re­quired volt­age. The Blum­leins are switched with solid state laser driv­en op­ti­cal switch­es that are an in­te­gral part of the Blum­lein as­sem­blies. Other sub­sys­tems in­clude a laser, a fiber optic dis­tri­bu­tion sys­tem, an elec­tri­cal charg­ing sys­tem and beam di­ag­nos­tics. An en­gi­neer­ing pro­to­type has been con­struct­ed and it has been fully char­ac­ter­ized. Re­sults ob­tained from the en­gi­neer­ing pro­to­type sup­port the de­vel­op­ment of an ex­treme­ly com­pact 150 MeV sys­tem ca­pa­ble of mod­u­lat­ing en­er­gy, beam cur­rent and spot size on a shot to shot basis with­in the next two years. The paper will de­tail the con­struc­tion of the en­gi­neer­ing pro­to­type and dis­cuss ex­per­i­men­tal re­sults. In ad­di­tion, fu­ture de­vel­op­ment mile­stones and com­mer­cial­iza­tion plans will also be dis­cussed.
